Does anyone know the yudansha promotion fees at the Aikikai Hombu Dojo? If so, would you please post them, in either Yen or US Dollars. I realize that there are different prices, depending on whether the candidate is promoted by examination or recommendation, so please state which category applies.

How often do these fees change? How does Hombu announce the changes?

Are the fees the same for students at Hombu Dojo and students outside of Hombu? Are the fees the same in Japan and outside Japan?
